      • Developer Note - With this change, only the Utility slot Duffel Bag will spawn. This does not impact the reward items redeemed at the end of the level.
    • Offline
      • Fixed an issue where Duffel Bags were not always spawning in Offline Mode.
    • Reward Items
      • Duffel Bags now only contain Expansion 2 cards and Expansion 2 character skins. When a player has all this content unlocked, the Duffel Bag will grant Burn Cards.
      • Other Expansion 2 non-exclusive cosmetic content (weapon skins, emblems/sprays/banners) are available to unlock with Supply Points through Roving Merchant supply lines.
      • Developer Note - This is a temporary fix implemented to ensure that players are able to unlock the Expansion 2 cards as they encounter duffel bags. We are working on a more permanent solution at this time.
